Antecedentes de la invenciónBACKGROUND OF THE INVENTION
La presente invención proporciona compuestos útiles como moduladores del canal de potencial de receptor transitorio melastatina 8 (TRPM8). El TRPM8 es un canal implicado en sensaciones quimioestéticas, tales como temperaturas de frescas a frías, así como las sensaciones de agentes refrescantes conocidos, tales como mentol e icilina. Sin embargo, muchos de los moduladores de TRPM8 conocidos actualmente tienen deficiencias con respecto a la fuerza y/o la duración del efecto, irritación de la piel y/o mucosa, olor, sabor, solubilidad y/o toxicidad.The present invention provides compounds useful as modulators of the transient receptor potential channel melastatin 8 (TRPM8). TRPM8 is a channel involved in chemostatic sensations, such as temperatures from fresh to cold, as well as the sensations of known cooling agents, such as menthol and icilin. However, many of the currently known TRPM8 modulators have deficiencies with respect to strength and / or duration of effect, irritation of the skin and / or mucosa, odor, taste, solubility and / or toxicity.

DefinicionesDefinitions
Los términos "uno" y "una" no denotan una limitación de la cantidad, sino que más bien denotan la presencia de al menos uno de los elementos a los que se hace referencia. El término "o" o "y/o" se utiliza como una palabra funcional para indicar que dos palabras o expresiones deben tomarse conjuntamente o individualmente. Las expresiones "que comprende", "que tiene", "que incluye" y "que contiene" deben interpretarse como expresiones abiertas (es decir, que significan "que incluye, pero no se limita a"). Los puntos finales de todos los intervalos dirigidos al mismo componente o a la misma propiedad son inclusivos y se pueden combinar de forma independiente. The terms "one" and "one" do not denote a limitation of the quantity, but rather denote the presence of at least one of the elements to which reference is made. The term "or" or "and / or" is used as a functional word to indicate that two words or expressions must be taken together or individually. The expressions "comprising", "having", "including" and "containing" should be interpreted as open expressions (ie, meaning "including, but not limited to"). The endpoints of all the intervals directed to the same component or to the same property are inclusive and can be combined independently.
Las expresiones "presente(s) compuesto(s)" o "compuesto(s) de la presente invención" se refieren a compuestos abarcados por la fórmula estructural divulgada en el presente documento, tal como la fórmula (I) o la fórmula (Ia), e incluye cualquier subgénero y compuestos específicos dentro de la fórmula cuya estructura se divulga en el presente documento.

El término "quimioestesia" o la expresión "sensación quimioestética" en el presente documento se refiere a la sensibilidad de la superficie corporal, por ejemplo, las superficies de la piel y/o de la mucosa que aparece cuando la superficie corporal está expuesta al calor o al frío o cuando compuestos químicos activan receptores asociados con los sentidos que median el dolor, el tacto y la percepción de calor/frio. En particular, estas reacciones inducidas por sustancias químicas no encajan en las categorías de sentido tradicionales de gusto y olfato. Los ejemplos de sensaciones quimioestéticas incluyen la irritación similar a una quemadura causada por el chile picante, el frescor del mentol en los enjuagues bucales y las cremas analgésicas tópicas, el picor u hormigueo de la carbonatación en la nariz y la boca, y la inducción de lágrimas por cebollas. Es decir, pueden aparecer sensaciones químicas mediante la activación química directa de los canales iónicos en las fibras nerviosas sensoriales, por ejemplo TRPM8. Debido a que las fibras nerviosas con sensibilidad quimioestética están presentes en todos los tipos de piel, las sensaciones quimioestéticas pueden despertarse desde cualquier parte de la superficie del cuerpo, así como desde las superficies mucosas de la nariz, la boca, los ojos, etc.The term "chemosesthesia" or the term "chemostatic sensation" herein refers to the sensitivity of the body surface, for example, the surfaces of the skin and / or mucosa that appear when the body surface is exposed to heat or when cold or when chemical compounds activate receptors associated with the senses that mediate pain, touch and perception of heat / cold. In particular, these reactions induced by chemicals do not fit into the traditional sense categories of taste and smell. Examples of chemostatic sensations include irritation similar to a burn caused by hot pepper, freshness of menthol in mouth rinses and topical analgesic creams, the itching or tingling of carbonation in the nose and mouth, and induction of tears for onions. That is, chemical sensations may appear by direct chemical activation of the ion channels in the sensory nerve fibers, for example TRPM8.

En una forma de realización de la invención, los presentes compuestos se proporcionan en una formulación de concentrado quimioestético, por ejemplo, adecuada para su procesamiento posterior para producir un producto listo para su uso (es decir, listo para servir). Por "una formulación de concentrado quimioestético", se entiende una formulación que debe reconstituirse con uno o más medios de dilución para convertirla en una composición lista para su uso. La expresión "composición lista para su uso" se utiliza en el presente documento de forma intercambiable con "composición ingerible", que denota cualquier sustancia que, ya sea sola o junto con otra sustancia, se pueda tomar por vía oral, ya sea para consumo o no. En una forma de realización, la composición lista para su uso incluye una composición que puede consumirse directamente por un ser humano o un animal. La formulación de concentrado quimioestético se usa típicamente mezclándola o diluyéndola con uno o más medios de dilución, por ejemplo, cualquier ingrediente o producto consumible o ingerible, para impartir o modificar una sensación quimioestética al medio de dilución. Dicho proceso de uso se denomina a menudo reconstitución. La reconstitución puede llevarse a cabo en un entorno doméstico o industrial. Por ejemplo, un consumidor en una cocina puede reconstituir el concentrado de zumo de fruta congelado con agua u otro medio acuoso para obtener la bebida de zumo de fruta lista para su uso. En otro ejemplo, un concentrado de enjuague bucal puede reconstituirse con agua u otro medio acuoso mediante una fabricación a gran escala industrial para producir el enjuague bucal listo para su uso. Dado que la formulación de concentrado quimioestético tiene el presente compuesto y opcionalmente un agente aromatizante y/o un agente modificador del sabor en una concentración superior a la de la composición lista para su uso, la formulación de concentrado quimioestético típicamente no es adecuada para consumirla directamente sin reconstitución. Existen muchos beneficios en usar y producir una formulación de concentrado quimioestético. Por ejemplo, un beneficio es la reducción en el peso y el volumen para el transporte, ya que la formulación de concentrado quimioestético se puede reconstituir en el momento de su uso mediante la adición de un disolvente adecuado, sólido o líquido. In one embodiment of the invention, the present compounds are provided in a chemostatic concentrate formulation, for example, suitable for further processing to produce a ready-to-use (ie, ready-to-serve) product. By "a chemostatic concentrate formulation" is meant a formulation that must be reconstituted with one or more dilution means to convert it into a ready-to-use composition. The term "ready-to-use composition" is used herein interchangeably with "ingestible composition", denoting any substance that, either alone or together with another substance, can be taken orally, either for consumption or not. In one embodiment, the ready-to-use composition includes a composition that can be consumed directly by a human or animal. The chemostatic concentrate formulation is typically used by mixing or diluting it with one or more dilution media, eg, any consumable or ingestible ingredient or product, to impart or modify a chemostatic feel to the dilution medium. This process of use is often called reconstitution. The reconstitution can be carried out in a domestic or industrial environment. For example, a consumer in a kitchen can reconstitute the frozen fruit juice concentrate with water or other aqueous medium to obtain the fruit juice beverage ready for use. In another example, a mouth rinse concentrate can be reconstituted with water or other aqueous medium by industrial large-scale manufacture to produce mouthwash ready for use. Since the chemostatic concentrate formulation has the present compound and optionally a flavoring agent and / or a flavoring agent in a concentration higher than that of the ready-to-use composition, the chemostatic concentrate formulation is typically not suitable for direct consumption. without reconstitution. There are many benefits in using and producing a chemostatic concentrate formulation. For example, a benefit is the reduction in weight and volume for transport, since the chemostatic concentrate formulation can be reconstituted at the time of its use by the addition of a suitable solvent, solid or liquid.

La expresión "como ingrediente modificador de la sensación quimioestética" indica que el compuesto de la presente invención actúa como un modulador de una sensación quimioestética (tal como un modulador de una sensación de frío o refrescante) en la formulación. El término "vehículo" denota una sustancia accesoria generalmente inactiva, tal como disolventes, aglutinantes u otro medio inerte, que se usa en combinación con el presente compuesto y uno o más adyuvantes opcionales para formar la formulación. Por ejemplo, el agua o el almidón pueden ser un vehículo para una formulación de concentrado aromatizante. En algunas formas de realización, el vehículo es el mismo que el medio de dilución para reconstituir la formulación de concentrado quimioestético; y en otras formas de realización, el vehículo es diferente del medio de dilución. El término "vehículo", tal como se usa en el presente documento, incluye, pero sin limitación, un vehículo aceptable para su ingesta.In one embodiment, the chemostatic concentrate formulation comprises i) as a chemoesthetic feeling modifying ingredient, a compound of the present invention; ii) a vehicle; and iii) optionally at least one adjuvant.

The term "carrier" denotes a generally inactive accessory substance, such as solvents, binders or other inert medium, which is used in combination with the present compound and one or more optional adjuvants to form the formulation. For example, water or starch can be a vehicle for a flavoring concentrate formulation. In some embodiments, the vehicle is the same as the dilution medium for reconstituting the chemostatic concentrate formulation; and in other embodiments, the vehicle is different from the dilution medium. The term "vehicle", as used herein, includes, but is not limited to, an acceptable vehicle for its intake.

EjemplosExamples
1.1) Ensayo biologico1.1) Biological test
Los presentes compuestos son útiles como moduladores de TRPM8. La actividad de TRPM8 puede supervisarse fácilmente en ensayos basados en células utilizando tintes fluorescentes sensibles al calcio, tintes sensibles a potencial de membrana o tintes sensibles al sodio. La actividad de TRPM8 también se puede supervisar con configuraciones electrofisiológicas, tales como la fijación de parches y la fijación de dos electrodos de voltaje. Un derivado de línea celular de mamífero que expresa de forma estable TRPM8 se usó en ensayos biológicos en asociación con el ensayo de los presentes compuestos con propiedades de sabor fresco o sensación a frescor (Servant et al. documento US 2007/0259354 A1 y referencias citadas en el mismo). Las concentraciones típicas de compuestos analizadas fueron 100 pM, 50 pM, 10 pM, 1 pM y 0,5 pM. Los presentes compuestos han mostrado una fuerte actividad como agonistas de hTRPM8. Los resultados de los ensayos para los compuestos se ilustran en la tabla 1 siguiente. Específicamente, los compuestos enumerados en la tabla 1.1, por ejemplo, compuestos 1.A1 a compuestos 1.A9 son los compuestos específicos tal como se describen en el presente documento. Por ejemplo, el compuesto 1.A1 es el ejemplo 1.1.The present compounds are useful as modulators of TRPM8. The activity of TRPM8 can be easily monitored in cell-based assays using calcium-sensitive fluorescent dyes, membrane-sensitive dyes or sodium-sensitive dyes. The activity of TRPM8 can also be monitored with electrophysiological configurations, such as patch fixation and the attachment of two voltage electrodes. A mammalian cell line derivative stably expressing TRPM8 was used in biological assays in association with the assay of the present compounds with properties of fresh taste or cool sensation (Servant et al., US 2007/0259354 A1 and cited references in the same). Typical concentrations of compounds analyzed were 100 pM, 50 pM, 10 pM, 1 pM and 0.5 pM. The present compounds have shown strong activity as hTRPM8 agonists. The results of the tests for the compounds are illustrated in Table 1 below.
